LS1S line source surround loudspeaker
Overview Specs Downloads

Employing the same ribbon driver technology present in our screen channel ​loudspeakers, Christie's line source surround loudspeakers feature a unique integrated waveguide design to provide enhanced clarity, and reduced distortion. In addition, the inclusion of the ribbon driver provides ultra-fast transient response. Our line array surround loudspeakers offer the same benefits while also providing perfect timbre matching and extremely uniform coverage for seamless listening experience throughout the auditorium.

Note: Safety cables are recommended any time a loudspeaker will be positioned overhead in an auditorium.​


  • Unique integrated waveguide design for very wide, controlled dispersion patterns
  • ​Ribbon driver and paper/Kevlar composite cone drivers
  • Dramatically higher RMS to​ peak max SPL ratio than compression driver systems
  • Ideal for use as surround channel loudspeaker, with or without bass management
  • Heavy duty marine grade plywood cabinet with integrated mounting points

No listening fatigue

Extended listening comfort throughout the movie

*Measured at 2m on tweeter axis in simulated free field conditions. Near field measurements were used for low-frequency data.  Sensitivity is calculated based on measured SPL response averaged in 200Hz-5kHz range.

**IEC refers to IEC 60268-5 standard. Max SPL calculated based on sensitivity and power handling. IEC short-term power tested  using IEC pink noise with 9dB crest factor. The crest factor was specifically increased to reflect real-life parameters of digital cinema sound tracks. Maximum peak SPL calculated using peak voltage during IEC short-term power test. Continuous power handling  tested using IEC60268-1 noise signal for duration of 2 hours.

***Averaged in 500Hz-12kHz range, at -6dB.
